Specification of Letters Patent.

Application filed-November 2, 1916. Serial No. 129,246.

declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in humidifiers, and the primary object of the invention is to provide an air moistening apparatus that can be readily and easily attached to a steam radiator, and yet be controlled independently of the radiator. v 1

Another object of this invention I is to provide a humidifying apparatus consisting of an arrangement of pipes which may be easily secured to a steam radiator, and which comprises a perforated pipe disposed across the top of the radiator, whereby steam may be ejected into the room to bring the moisture therein to the recognized normal standard.

Still another objectof this invention is to provide a humidifying apparatus for ejecting steam into a room, which is secured to a radiator, and which is so arranged that the water of condensation will becarried back to the radiator,'but no steam will be returned therewith.

Another object of this invention is to pro- Vide a device of this character which is simple and durable in construction, inexpensive to manufacture, and one which will be very eflicient in operation.

With these and numerous other objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to and more particularly pointed out in the specification and claim. In the accompanying drawings:

Figure 1 is a side elevation of a steam radiator showing the attachment applied thereto;

Fig. 2 is a top plan view of the same; Fig. 3 is a rear end elevation; Fig. 4 is a front end elevation; Fig. 5 is a section taken on the line 5-5 of Fig. 1; and Fig. 6 is a detail sectional view of the check valve. 1

In the practical construction and application of my invention any form or style of steam radiator can be used, and the form illustrated in the accompanying drawings shows my device applied to one type of steam heating radiator.

The radiator 1 is of the conventional type, it being provided at one end which is called the inlet end 2, with a steam inlet 3 being 7 provided with the usual type of cut-0H valve 4. Extending along the top of the radiator l, and projecting a short distance beyond the opposite ends of the same, is a perforated pipe 5 having spaced perforations 6 disposed longitudinally in spaced relation along its upper surface.

The end of the perforated pipe 5 which projects past the inlet end 2 of the radiator,

1s connected therewith by a vertical inlet pipe 7, which is smaller than the perforated pipe 5, and which has its upper end con-.

'nected to the adjacent end of the perforated pipe, as shown at 8. The'lower end of the steam inlet pipe 7 is connected as shown at 9 with the inlet end of the steam radiator intermediate the ends of the end section thereof. This connection 9 is any ordinary type of tap found most suitable. The steam inlet pipe 7 is disposed at right angles to the perforated pipe 5, and to the tap at the inlet end of the radiator, and the ends of the same are connected therewith by the ordinary type ofl. couplings.

Disposed intermediate the ends of the steam inlet pipe 7 is a cut oil" valve 10 which is of anyordinary tvpe, and which supplies means for regulating the flow of steam through this pipe from the radiator. By the operation'of this valve, when the radiator is being operated, the flow of steam through the pipe to the humidifier may be regulated at the will of the operator. Positioned above the cut ofi valve 10 on the steam inlet pipe 7 is a union connection 11 positioned 5. The connections between the adjacent ends of the above mentioned pipes are the conventional .type of L couplings.

The lower end of the return pipe 12 is connected with the end of the radiator adjacent the bottom of the same through the medium of an additional short. length pipe 14, that is horizontally disposed and is substantially parallelwith the shortlength pipe 13, and

the same extends to a point substantially in the same vertical plane with the perforated pipe 5'disposed at the top of the radiator. The outer end of the short pipe 14 is turned inwardly at right angles thereto'and is connected with the end at 15.

Positioned intermediate the ends of the of theradiator as shown short length pipe 14 is a check valve 16 that is provided with a vertically swinging 'flap 17 mounted on a horizontal pivot 18,

and which provides means whereby the steam will be prevented from returning from the short length pipe 14, the adjacent end of the return pipe 12, and the end of the radiator. are the conventional type of L couplings commonly used.

By experiment it has been demonstrated that the moisture in'rooms heated by radiators employing the steam system is far below the recognized normal standard, which condition is productive of much discomfort and is also detrimental to health. When the proper amount of moisture is supplied to a room heated by steam radiators, a much lower temperature can'be maintained without discomfort to the occupants. By the attachment of my form of humidifier to any type of steam radiator, the ejection of live steam into the room'will raise the moisture to the desired density. The amount of steam may be regulated, and when the moisture in the room reaches the desired normal standard, the flow of steam may be cut off.

This humidifier consists only of the system of pipes, that are positioned on any type of steam radiator, and the same may be easily and simply applied thereto. When steam heating system at the opposite end of the radiator. The return 'pipe 12 isofltset, and the lower horizontally extending ofi'set short pipe of the same is provided with a check valve which has a valve flap mounted on a horizontal pivot, whereby the steam radiator to the humidifier, but the water of will be prevented from returning from the condensation may readily pass therethrough.

From the foregoing description of the construction and operation of my improved humidifier, the manner of applying the same to use, and the operation thereof will be readily understood, and it will be seen that I have provided a simple and efiicient device of this character for carrying out the ob ect of the invention.

I claim:

A humidifier comprising a perforated pipe to be disposed above a steam radiator a steam inlet pipe connecting one end 0 said perforated pipe with the inlet end of the, radiator, a. cut-off valve in said inlet pipe, a condensation return pipe hav ng one end connected to the other end of said perforated pipe, a short horizontal'plpe connecting the lower end of said return p1peto the end of said radiator, a check'valvem said horizontal pipe whereby condensatlon will be permitted to return to the radiator, and steam in said radiator will be prevented from passing to the perforated-pipe through said return pipe.

In testimony whereof I have hereuntoset in hand in the presence of two subscribing witnesses.
